hi guys i got a reanult laguna on a w plate, today one of the coil packs failed, so i used a coil of my mates laguna to test and find which one had failed, re-placed the coil pack and it made no difference, i could pull the coil pack of the plug with no engine tone change pulling the other 3 off nearly stalled the engine, so i replaced the spark plug but its still the same, like the car is running on 3 coil

Can someone give me an idea as to what the problem is, i checked the wiring the best i can cannot find anything

If you are certain the spark plug is in good nick and is getting a strong spark then the next step is to check the injector is delivering fuel and the cylinder has good compression.
